After Flashing Stock Rom From fastboot phone powered on normally, as the firmware was of marshmallow, I was updating it to nougat, but while installing system update, it powered off and now it won't turn on!
The bootloader was unlocked, and I flashed the supersu zip which caused the bootloop which forced me to flash the stock rom!

please Help!
